Western Research and Demonstration Farm
More pigs are being produced in bedded systems such as hoop barns due to the increase in demand for niche pork. Most of the current swine nutrition information has been generated in confinement settings without bedding. As omnivores, pigs ingest some bedding. There are questions about the effects of the ingested bedding on growth and feed utilization by the modern market pig. More knowledge in this area will allow for more accurate feed formulation in bedded systems.
